- 摘要:
- 以平欧杂种榛（Corylus heterophylla×Corylus avellana）一年生枝条为试材，研究不同浓度IBA和ABT 1号生根粉单独和复合浸泡处理3 h对其容器扦插生根的影响。结果表明：各处理中，以100 mg?L-1 ABT 1号生根粉效果最好，生根率达77.22%，插穗平均一级侧根数达10.33条，插穗平均根长达8.25 cm，最粗根根粗达1.91 mm，分别较对照极显著提高了22.19、2.87、2.99、3.55倍。不同浓度IBA处理后，以400 mg?L-1处理时生根率最高，达25.00%；IBA与ABT 1号生根粉复合处理后，以100 mg?L-1 IBA+25 mg?L-1 ABT处理时生根率最高，达20.00%。由此可见，平欧杂种榛硬枝容器扦插宜采用100 mg?L-1 ABT 1号生根粉浸泡插穗3 h。
- Abstract:
- The annual hardwood of Corylus heterophylla×Corylus avellana was selected as cuttings，the effects of different concentrations of IBA and ABT 1 on cuttings individually or combinedly for 3 hours on rooting of cutting container were investigated.The results showed that ABT 1 with 100 mg?L-1 was the best in all the treatments，the rooting percentage was 77.22%，average primary lateral root number of cuttings was 10.33，average root length was 8.25 cm，the thickest root diameter was 1.91 mm，compared with the control significantly increased by 22.19 times，2.87 times，2.99 times，3.55 times;the suitable concentration of IBA was 400 mg?L-1，the rooting percentage was 25.00%;the suitable concentration of the combined treatment of IBA and ABT 1 was 100 mg?L-1 IBA+25 mg?L-1 ABT 1，the rooting percentage was 20.00%.In addition，the suitable treatment was steeping the cuttings for 3 hours with 100 mg?L-1 ABT 1 for Corylus heterophylla×Corylus avellana hardwood on rooting of cutting container.
